CAR'QREPLACER.

srncIrIoA'rroN forming part of Letters Iatent No. 634,100, dated Octobere, 1899.

"To all whom it may concern Be it known that I, ISAAC H. WISE, ofHuntsville, in the county of Madison and State of Alabama, have inventeda new and Improved Gar-Replacer, of which the follow-' ing is a full,clear, and exact description.

My invention relates to an improvement in devices for replacing cars andsimilar wheeled vehicles upon a track, and comprises the novel featureshereinafter more fully deplaced when in use. Fig. 3 is an end elevationof a car, showing my device in place ready for use. Fig. 4c is a sideelevation of my device, showing an axle in section on the line 4 dinFig. 3. Fig. 5 is a detail view of a modified formof construction, andFig. 6 is a detail view showing more clearly the yoke or block which isinserted in the notch in one of 1the segment-disks and which receivesthe ax e.

My device comprises, essentially, pairs of segment-disks I and O, whichare connected with each other by means of shafts E or by any othersuitable connection, one of the disks having teeth formed in itsperiphery and adapted to engage with a toothed rib or rack B, whichprojects slightly from the surface of a base A. 1

Each segment disk O is provided'with a notch F, located at one end ofthe segmental portion and of sufficient size to receive therein the axleof the car. This notch may have a block or yoke Gr placed therein andhaving an opening of such size as to engage the caraxle. Thisconstruction .while not strictly essential is desirable for somereasons. It is preferred thatt inner surface of the notch F should berounded or beveled, as clearlyshown in Fig. 6, so .that the axle or theyoke G, when such a yoke is used, may rock slightly upon these surfacesto accommodate the angular positions of the axle H.

The base upon which the segmentdisks are placed consists of a plate A,which, as herein Fig. 2 is a plan of the base upon which the device isApplication filed February Q1899. Serial No. 704,779. (No model.)

shown, is of semicircular outline and has the rib B projecting above itsupper surface and toothed to correspond with the teeth upon theperiphery of the segment 0. It is also provided upon its undersurfacewith teeth or projections a, adapted to engage the side edges ofthe railroad-ties T, and thus prevent the base from sliding upon saidties. Itis preferred that the device be used in duplicate, audit isherein so shown, two bases A and the corresponding segments being used,the two being made right and left, so as to fit together.

The segment I is without any teeth upon its periphery and also withoutthe notch F, which engages the axle. The purpose of this segment is toprevent the segment 0 from rocking sidewise under the influence ofeither the weight of the car or the pull of the engine when the car isbeing raised -to its. properplace. One edge of this segment projects 7under the axle H, so as to prevent the segment I from rising under theinfluence of a side strain, while its bearing upon the base A willprevent the segment from being rocked in the opposite direction.

The device is placed upon the ties beneath the axle of the car and maybe and preferably is placed with the ribs 13 extending at such an angleto the rails as to carry the car toward the rails J at the same timethat it is lifted. It is only necessary to raise the car a sufficientdistance to cause the flanges of the wheels K to clear the rails J.

- It is obvious that with the device placed in the position shown inFig. 1 and the car pullediu the direction indicated by the arrow thecar-axle will be lifted as the segments roll upon the base. The angularposition of thedevice will determine the amount of side 'movement givento the car by this action.

Thecar by this means may be raised and transferred sidewise as manytimes as necessary to get it upon the track.

The device is comparatively simple, weighs but little, and may be placedin position by two men. When in position, it is a simple matter, byattaching the engine to the car,

to lift the car and put it in place on the track.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A car-rcpiacer, comprising a base havin a toothedrib or rack, and a segment-disk having teeth upon its periphery adaptedto engage with the rack-teeth, and a notch at one edge of thesegment-disk adapted to receive the car-axle.

2. A car-repiacer having a base, a toothed rib or rack on the base, anda segment-disk having teeth upon its periphery, flanges at each side ofthe teeth adapted to engage and embrace the rack-teeth, and a notch atone edge of the segment-disk, adapted to receive the car-ax1e.

3. A car-repiacer, comprising a base having a toothed rib or rack, atoothed segment-disk engaging the rack and having a notch at one edgeadapted to receive the car-axle, the sides of said notch'being beveledor rounded, and a yoke fitting Within said notch and receiving thecar-axle.

4. A car-replacer, comprising abase having a toothed rib or rack, atoothed segment-disk engaging the rack and having a notch at one edgeadapted to receive the car-axle, and a similarly-curved segment-disksecured to the toothed segment by a shaft or axle, and adapted to bearupon the base.

A car-replacer, comprising a base having a toothed rib or rack, atoothed segment-disk having flanges at each side of the teeth andengaging the rack, a notch at one edge of the segment-disk, adapted toreceive the car-axle, and a similarly-curved segment-disk secured to thetoothed segment and adapted to bear upon the base.
